Did Champion 7989 plugs on mine and some yellow coils can't remember the brand right off. Working great no problems.

Just installed a set of Summit Racing brand coil packs and Motorcraft plugs, in my daughters 2001 King Ranch. Prior to changing them it had started to randomly miss. So far all they've been great.

Glad your having good luck with the Summit cop's. I bought one a few weeks ago and was less than impressed. Had to take the dremel to it to get the electrical connector on. Maybe mine was made on a Friday :dunno:
